Specification forming part of LettorsPahnt Neal58s6Q4', dated J auuary12, 1875; application filed October 1 1874.

To all whom it may concern I v Be it known that I, WILLIAM N. Goscnovn,of Faribault, in the county of Rice and State 'of Minnesota, haveinvented certain new and useiul Improvements in'Dish-Washers, of

which the following is a specification: t

This invention has for its object to furnish ahighly eflicaciousapparatus, whereby dishes and similar articles may be washed with ce--lerity in a perfect and thorough manner; and

to this end my invention consists. in the comblnation and arrangement ofdevices hereinafter described and explained.

In order to enable others skilled in the art to make and use myinvention, I will proceed -to'describe the particular manner in which Icarried it out.

In the accompanying'drawings, Figure 1 is a lon gitudinal sectional.view otia dish-washer" constructed according to my invention Fig. 2 1sa detail sectional view, representing the dish-tank or holder-rack, andrelative arrangement of the pump and strainer.

The tank or holder A, which is generally made of a rectangular shape andof metal, is

designed to afl'ord proper facilities for con-..

taining and heating the water which is to be usediin the cleansingoperation. In one cornor of the tank there is locateda force-pump,consisting essentially of a stationary cylinder,

'B, a piston, C, and a hollow piston-rod, D, to I the upper end 'ofwhich is attached an inverted cone-shaped, bulb, P, into which the waterfrom the pump flows until it becomes filled,

"when the water seeks an exit through theflexible discharge-hose E. Theobjectof the bulh P thusintroduced; between the hollow piston-rod D andthe-discharge-hose E is to secure a regular and'constant'fiow'of thewater .during the operation of washing. It is evident that but for theintroductlomefiahe bulb, the action of'the pump would be more or lessintermittent. The bulb, however, acts as a-reservoir, from which a,supply of water from the pump is caused to flow with greater regularity.Thus it becomes an essential feature of my invention. The cylinder Bpossesses the u'su'al'induction-valves.common to pumps, and the pistonwhich operates in the same is packed with vulcanized india-rubber, soasto render theactionof the pump'simple andperfeet. The tubular pistoirrod is connected with dle, G, located in proper respect thereto. Saidsleeve, which is made of wood or othersuitatble material, serves as ahandle for manipu-' lating the hose' with impunity, for wood'being ingthrough the hose cannot burn the hand of the person handling the hose.

The dishes to be cleansed or washed are placed upon a rack, H, which isplaced in the tance above the water-line. The rack, which,

0 f, fitted securely in a surrounding frame, one

in width, or provided with oii'sets or shoulders d, as shown in Fig. 2,the object of this construction being to enable the rack to fit properlyinto the tank at the point or corner where the pump isJocated. Thedouble rack is chiefly designed to support dishes inan uplongitudinalandtransverse bars for support 'upper rack is composed of longitudinalbars,

which serve to prevent the dishes from slipping out otplace. The waterafter having stove, or otherwise, issdischargc'd through the nozzle ofthe flexible hose in such a manner as to impinge or. act upon the disheswith suflipurities. The water after having acted upon repeatedly useduntil it is dirt-3', or all the dishes are cleansed.

In order to prevent solid matters, fats, and other impurities floatingin the water from same a' wire-gauze screen or strainer, l, whichPATENT. OFFICE;

above the other, has one of its sides reduced right or edgewiseposition, and for this purpose the lower rack or grate e is composed ofing the lower ends of the dishes, while thebeen heated by placing theapparatus .on a

the dishes falls .to the bottom of the tank, from whence it is againdrawn up, so as to be passing into the pump, l locate in front of the Iis attached to the side walls of the tank. Thisstrainer etfectuallyprevents the entrance of anything else than water into'the pump; but inorder to guard against the entrance of fine sediment, which generallysinks to the bottom, I provide the screen with a narrow imperforateborder, J for the objectstated. The great a'lvant-a'ge derived by myinvention is that the water can be thrown wherever wanted, and be drawnfrom the bottom of the tank free from all impurities:

What I claim is A dish-washer, constructed as described,

and consisting essentialiy ofgthe tank A, forcepnmp'provided withthe'--balii"orfreservo ir-P,-- the strainer Lihavinglthe solid board J,and the pipe E with its handle G and nozzle a, substantially as hereinset forth.

In testimony that I.cl'aim the foregoing I have hereunto set my hand. i
